When the masses run out of food, electricity, gasoline, air conditioning, and the NFL, they will begin to look around, and find the few, have the food, and all else will matter little.
Foraging on wildlife, will be almost non-existent in most places. The American Indian was the premier forager in his day, and they occasionally starved to death. The deer have never made much of a come back here in my part of Texas, since they were hunted to near extinction in this area during the last depression.
One only has to look at hurricane evacuation film footage, to realize that the highway system will be impassable in site of the first week. Folks will merely drive the vehicle until it quits, and leave it where it stops. Triple A, will not be answering the phone.
Many will find out quickly that the Cops were not as bad as they thought, when they realize that their not the only ones that have a high powered rifle that will shoot thru their house, WITH THEM IN IT, and no one is picking up the phone at 911 centers, and the cops aren't coming. So to those. Careful what you wish for.
Light, fast, and mobile, may be the order of the day. Many say they will hole up at home. Will you, when someone is outside with a rifle, that will shoot completely thru it?
There are countless things to consider. Can one carry enough food, and water, and weapons, and ammo, much less reloading supplies? One must also consider SHOES, and clothing, and medicines, and first aid supplies. Can you realistically carry all of that?
I believe one must partner up with others of like mind, just to survive. The masses will be scouring the country for scraps, and by the time they, and possibly their children get hungry, they will take what they need, at what ever the cost. Books, articles and movies, are just that, but are not necessarily reality.
We live in a country of 300,000,000 PLUS, and they will begin to stir in every direction, when Uncle Sam abandons them.
